Located in Dún Laoghaire, Co. Dublin, dlr LexIcon is the new Central Library and Cultural Centre of Dún Laoghaire-Rathdown County Council (DLR CC). Built by the DLR CC under the urban regeneration scheme and praised for its environmentally responsible construction, the €36.6m building is home to over 80,000 items in the adult and junior libraries. There are plenty of amenities in the dlr LexIcon Library including over 60 computers, a study zone, meeting rooms, a café and a floor dedicated to Local Studies.
The site chosen was Moran Park, a partially derelict public park which was already owned by DLR CC. Designed by Carr Cotter & Naessens and opened in December 2014, the impressive building won 1st place in the 2015 Royal Institute of the Architects of Ireland award categories Best Culture and Best Public Building and 3rd place in the Pubic Choice category. At the 2015 Irish Building and Design Awards Carr Cotter & Naessens won Architectural Project of the Year for the dlr LexIcon.
For the project a number of Kingspan Insulation products were used throughout the complex. 100mm of Thermawall TW55 was used in the development as insulation for the timber and steel framing systems, TW55 has a thermal conductivity of 0.022W/m.K and can be used between studs or as an insulating sheathing.
Thermaroof TR27 was used over a 50mm area. With fully adhered singly-ply, partially bonded built-up felt, mastic asphalt and cold liquid applied waterproofing; this insulation was used across the flat roof area of the building.
For the pitched roof area of the building 75mm of Kooltherm K7 Pitched Roof Board was used. This premium performance rigid thermoset insulation was used for the tiled warm roof spaces of the building. With a thermal conductivity as low as 0.020 W/m.K and a class 0 fire rated insulation core this product was the perfect solution for the Dlr LexIcon development.
Also used on the project, Kingspan Styrozone N 300 R has a smooth, dense skin on both faces and was used throughout this project. This heavy duty, high performance rigid extruded polystyrene insulant was used in a number of thicknesses ranging from 30mm up to 120mm. This product can be used in heavy duty floors, inverted roofs and basement walls.
This project made the shortlist for the 2015 World Festival of Architecture Awards in the Civic and Community - Completed Buildings Category.
